1,200 pregnant women (600 HIV+ mothers and 600 HIV-controls) in their third trimester were enrolled from January 2016 to June 2019. Participants are being followed as mother-baby pairs at birth, within 10 days of life 6, 10, 14 24, 48, 72 and 96 weeks of age. At each visit clinical examinations are being used to assess health and the impact of environmental factors. In addition, questionnaires are administered and bio-samples for laboratory tests. The design of the study is non-interventional cohort but participants are being offered advice regarding health and hygiene.

To determine maternal- infant microbiota16S sequencing in pregnancy and relate it to infant immune development and atopy (anti-inflammatory (IL-4, -5, -13) and regulatory cytokines (IL-10, TGF-β) at delivery, 6 weeks 48 and 96 weeks of age.

Bacterial full genome metagenomics shotgun sequencing to identify the microbiota metabolic potential (i.e. bacterial genes present will be done) and mass spectrometry will be performed for analysis of small intestinal content (metabolome).

Wide range of nutritional profiles and HAART levels spectrometry will be performed for analysis of at least 700 metabolites including amino acids and lipids will be performed in plasma, breast milk and stool samples

To characterize pathogen genetic diversity including HIV, HBV, HCV, CMV subtypes, prevalent in our study population at time of infection

To determine host genetic markers for infectious disease susceptibility including human leukocyte antigen (HLA) and killer immunoglobulin like receptor (KIR) gene variants and their association with infection rates of HIV and co-infections in mothers and their infants.

Only anonymous data will be stored at local sites and transferred between sites for collaborative research efforts. All original data will be stored locally at the UZ-CHS for at least 10 years on suitable electronic devices. Data transfer with collaborating partners will be encrypted. using EGAcryptor. With our European partners we will follow the current European General Data Protection Regulation effective May 25, 2018.

18 cGY ED-TBI followed by an allogenic done marrow transplant

Acute Leukemia

Myelodysplastic Syndrome

Patients will receive 18Gy ED-TBI in 8 fractions of 2.25 Gy each, twice/day for 4 days. Following the final fraction of TBI and an allogeneic hematopoietic stem cell graft.

ED-TBI Followed By Allogeneic Stem Cell Transplantation For The Treatment Of Refractory AML And Advanced MDS

Extended Dose - Total Body Irradiation Followed By Allogeneic Stem Cell Transplantation For The Treatment Of Refractory Acute Leukemia And Advanced Myelodysplastic Syndrome

The primary objective of this study is to determine the progression-free survival at 1 year, post alloHSCT, after ED-TBI followed by an alloHSCT for patients with refractory AML

The time to neutrophil and platelet engraftment following ED-TBI and alloHSCT

The day 30 morbidity (frequency, severity and affected organ function) of ED-TBI
The day 30 mortality associated with ED-TBI and alloHSCT.
The day 100 morbidity (frequency, severity and affected organ function) of ED-TBI
The day 100 mortality associated with ED-TBI and alloHSCT.
The late (> 6 month and >1 year) morbidity and mortality of ED-TBI/alloHSCT

Relapse rate after alloHSCT
The pattern of relapse (blood and marrow vs. extramedullary)
The overall survival

Incidence and severity of acute and chronic GVHD

All patients who receive at least one fraction of ED-TBI will be used in the safety analysis.
The incidence of adverse and serious adverse events will be tabulated by, severity and relationship to the treatment.
Adverse and serious adverse events will be monitored on an ongoing basis by the investigators.
Adverse events will be categorized using the CTCAE v.4. Adverse events will be summarized at the following intervals post stem cell transplant: day 30, day 100, 180, 365 and 730.

Objective data to determine CR rate, rate of relapse, time-to-progression and overall survival will be collected and reported.

Approximately, 5 patients from our institution will be eligible per year. Additional patients from cooperating centers could, potentially, add another 5 patients/year. Therefore, the duration of accrual is expected to be between 2-3 years.

Amputation, Traumatic

This program is the primary site for a novel immune modulation protocol for hand and/or forearm transplantation using donor bone marrow stem cells. This protocol, otherwise called the "Pittsburgh Protocol" has been published and implemented in 8 hand/forearm transplantations. The Pittsburgh hand transplant program is the only center that has experience with the "Pittsburgh Protocol" to reduce the number and dosing of immunosuppressive drugs used to prevent rejection of hand/forearm transplants.
